It's up to you. So we have the equivalent of a very small SSD in each of our ESP8266s and ESP32s but it mostly remains unused. Hi, I've been using ESP-NOW on some project and I find it very easy, nice and secure. EEPROM is provided for backwards compatibility with existing Arduino applications. Longtime User. . The MicroPython documentation for the ESP32-C3 indicates that the default pin assignments for Hardware I2C ports 0 and 1 are 18/19 and 25/26, but attempting to use those pins in the REPL resulted in errors, or no data. I believe that .write only works with individual bytes (0-255) of memory and I have to manage it, which is OK. Think of SPIFFS as a very small SD Card onboard the ESP32 chip itself. The clue is in the etching on the board itself. We use both filesystems in a similar way. To review, open the file in an editor that reveals hidden Unicode characters. The total flash memory size is (for most of the mass produced modules) 4MB, although some are produced with 8 or 16. .
